Hello all
I've got a few of these inductors and I wondered if anyone would be so kind and help me find out the inductance 🙂.
The dcR is close to zero as they are not wirewound but 25mm wide band(foil?). Average coil dia is ~40mm. It's 1--20 turns, a bit difficult to see.
Thanks😀

If you download a program like speaker workshop (www.audua.com) and make a simple jig, you can easily measure the inductance (at least between 10hz -> 20khz) yourself, along with the DC resistance, and therefore Q factor of the inductor.
Done right, the speaker workshop way is pretty darned accurate, and very inexpensive.

One other quick note - the process of making the required jig is documented in the speaker workshop help file.
